Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::PatchBasedDenoisingImageFilter< TInputImage, TOutputImage >

Derived class implementing a specific patch-based denoising algorithm, as detailed below.

This class is derived from the base class PatchBasedDenoisingBaseImageFilter; please refer to the documentation of the base class first. This class implements a denoising filter that uses iterative non-local, or semi-local, weighted averaging of image patches for image denoising. The intensity at each pixel 'p' gets updated as a weighted average of intensities of a chosen subset of pixels from the image.

This class implements the denoising algorithm using a Gaussian kernel function for nonparametric density estimation. The class implements a scheme to automatically estimated the kernel bandwidth parameter (namely, sigma) using leave-one-out cross validation. It implements schemes for random sampling of patches non-locally (from the entire image) as well as semi-locally (from the spatial proximity of the pixel being denoised at the specific point in time). It implements a specific scheme for defining patch weights (mask) as described in Awate and Whitaker 2005 IEEE CVPR and 2006 IEEE TPAMI.

◆ GenerateInputRequestedRegion()

template<typename TInputImage , typename TOutputImage >

void itk::PatchBasedDenoisingImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( )

overrideprotectedvirtual

What is the input requested region that is required to produce the output requested region? The base assumption for image processing filters is that the input requested region can be set to match the output requested region. If a filter requires more input (for instance a filter that uses neighborhoods needs more input than output to avoid introducing artificial boundary conditions) or less input (for instance a magnify filter) will have to override this method. In doing so, it should call its superclass' implementation as its first step. Note that imaging filters operate differently than the classes to this point in the class hierarchy. Up till now, the base assumption has been that the largest possible region will be requested of the input.

This implementation of GenerateInputRequestedRegion() only processes the inputs that are a subclass of the ImageBase<InputImageDimension>. If an input is another type of DataObject (including an Image of a different dimension), they are skipped by this method. The subclasses of ImageToImageFilter are responsible for providing an implementation of GenerateInputRequestedRegion() when there are multiple inputs of different types.

◆ UseFastTensorComputationsOn()

template<typename TInputImage , typename TOutputImage >

virtual void itk::PatchBasedDenoisingImageFilter< TInputImage, TOutputImage >::UseFastTensorComputationsOn ( )

virtual

Set/Get flag indicating whether the fast algorithm for tensor computations should be used.

 Specifically, when this flag is true (default) or On, a faster implementation of the 3x3
 symmetric positive-definite eigensystem analysis will be used. See
 Hasan KM, Basser PJ, Parker DL, Alexander AL.
 Analytical computation of the eigenvalues and eigenvectors in DT-MRI.
 J Magn Reson 2001; 152: 41-47.
 This faster algorithm may be slightly less accurate and possibly less stable in the presence
 of noise.  So far in practice it has been shown to work well.

 However, you may want to turn this option off if you have concerns about numerical
 performance.

◆ UseSmoothDiscPatchWeightsOn()

template<typename TInputImage , typename TOutputImage >

virtual void itk::PatchBasedDenoisingImageFilter< TInputImage, TOutputImage >::UseSmoothDiscPatchWeightsOn ( )

virtual

Set/Get flag indicating whether smooth-disc patch weights should be used. If this flag is true, the smooth-disc patch weights will override any weights provided via the SetPatchWeights method.
